Windows 10: KB4571756 Windows Update error 0x80073701 Standalone Installer error 0x8024200B

Windows update failed KB4571756 with error 0x80073701. Downloaded Standalone Installer windows10.0-kb4571756-x64.msu failed with error 0x8024200B.

I've already tried these steps:

- Windows Update troubleshooter

- sfc /scannow <- no errors

- Dism /Online /Cleanup-Image /ScanHealth <- no errors
- Dism /Online /Cleanup-Image /CheckHealth <- no errors
- deleted content SoftwareDistribution and catroot2
tried again via Windows update and standalone install but got the same error.

The device is a Surface Pro3 without any previous Windows Update issues.

Updating Fails with Error 0x80073701

Hi, there appear to be errors in your log. What was the final statement on the screen?

Looks like the two key things are the error number 0x80073701
and ERROR_SXS_ASSEMBLY_MISSING

Have you also checked absolute basics:
- check your disk (e.g. HDTune v2.55 free Health and Error Scan tabs
- if ok, run
chkdsk c: /scan
from an admin command or Powershell prompt

Post the summary results of those.

If ok please run this MS tool and post summary results:
